, resiliency in lieu ofthe well known pneu-A matic tires, so as tovavoid tire trouble, such as punctu'res and blow-outs, incident. to the use of pneumatic tires.

Vith the foregoing and i -other objects iii 'view, which will be apparent as. the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described'and' claimed, it being understood that changes can be made within the scope of what is'claiined, without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawings, wlierein- Figure l is a side elevation of the improved wheel, portions being broken away and shown in section.

2, 3 and 4 are sectional views on th 'respective lines 2 2, 3-3 and 4 4 of Fig. l, on an enlarged scale.

Fig. `5 is a sectional View similar to Fig. 4 showing a modification.

The body of ythe wheel comprises the sheet metal disks or plates 10 at the opposite sides which have central openings to accomiiiodate the hub l1. Said hub may be of any suitable construction and has, at its opposite ends, the annular flanges or shoulders 12 against which the inner edge portions of the disks 10 bear. Screws 13 engagel through the disks'lO and are screw- F threaded into the flanges or abutments 12.

As shown in Fig. 2, the hub 11 is mounted on the spindle 14 of the axle by a .ball or roller bearing, and a cap 15 is screwthreaded on tlieouter end of the hub toi'ei'iclose the bearing.

The tire is composed of the longitudinally `spaced segments or blocks 16 offrubber, wood, or other suitable material, over which is disposede casing or shoe 17 ofjrubber,

leather, or other suitable material. The shoe17 lhas beads 1S uat its edges. engaging within vvthe clincher flanges 19. of retainer rings 20 bearing against the outer Asides of' Vthe disks 10 near -theouter edges of said disks. The rings 2O are securedl'to the disks by means eftransverse bolts 21 engagingv through said rings and disks, and spacer sleeves 22 are preferably disposed on said bolts between 'the disks to' prevent the disks from lcollapsing vvwhen the bolts 21 are tightened. `When the 'shoe 17 is worn out,

the bolts 2l are loosened', sothat the beads 13 can be withdrawn from the flanges 19,

tlierebyeiiabling said shoe to be replaced by f a new one, or the old shoe can be repaired.y

The segments l16 are carried bythemetal l carriers 23 which forinbases for the seg?.

rments.f `The carriers 23l are divided longi1 tudinally between their edges into the opposit'e side l"sectionsy 24, Vwhich are formed with the outwardly 'oifsettlangesl'25 attheir opposite side edges for receiving and holds ing the tongues 26 of the segments 16. Said tongues 26 are of dove-tail cross-sectionsoas tolook between 'the flanges 25 when the secv 'I tions 24 are secured together. The sections 24 of each carrier have inwardly extending ears 27 at their ends and'inwardly eXtending ears 29 between their ends, and said ears are secured together by the bolts 28 and 30,

respectively, engaging through said ears, to secure the sections 24 together on the tonguek 26, thereby holding the segment assembled with the carrier.

The carriers 23 and segments 16 are'yieldable radially inwardly, being moved out-l wardly by springs. Thus, radial rods 31 have their outer eiid'portions pivotally engaging the bolts 28 between the ears 27, and

the inner terminals of said'rods slide vloosely through aperturesiii a ring 32 located be tween the outer and inner edges of the disks,

being secured to the rods by any .suitable nut locks. Coiled springs 36 are disposed and permit the segments to be `forced in-` around the rods 31 with their inner ends seating against washers 37 that bearagainst the ring 32, while thev outer endsv ofthe springs 36 bear against collars 38 secured on the rods 31. Said springs being confined between the collars 38 and the ring 32 will move the rods 31 and segments 16 outwardly,

wardly toward the hub, for the cushioning action of the wheel and to absorb shocks.

In order to limit thelongitudinal movement of the segments 16 circumferentially of the tire, the sections 24 of each carrier are provided between their ends with outstanding pintles 39 on which rollers 40 are mounted for turning movement. Said rollers 40 are disposed for movement within the re'- cesses 41 of the plates 42 secured to the inner sides of the disks 10 at the outeredges of said disks. The plates 42 are secured to the disks by means of rivets 43 or other se? curing elements, and by means of transversebolts 44 extending through the disks and plates, with spacer sleeves 45 on the bolts between saidplates. The rollers 40 are movable inwardly in the recesses 41, and the opposite side walls of said recesses are curved, ,as at 46,.around the corresponding bolts 28 as centers, to permit either end of each segment to swing inwardly about the axis of the bolt 28 at the opposite end of the segment. Thus, the segments can not only move inwardly bodily, but they cany oscillate, inasmuch as either endof the segment can swing inwardly.

As shown in Fig. 5, the segments 16l can be hollow and may be composed of resilient sheet metal.

Having thus describedV the invention, what is claimed as new is 1. A wheel comprising a body, a tire composed of segments, rods slidable in the body and pivotally connected with the segments near the'ends of the segments, spring means associated with said rods for moving the segments outwardly, and interengaging members carried by the body and segments between the ends ofthe segments to limit the longitudinal movement of the segments relatively to the body, said members of the body having portions curved about the corresponding pivots between the rods and segments and along which the members of the segments are movable when the r segments swing inwardly about said pivots.

2. A wheel comprising a body, a tire composed of segments, rods slidable in the body, pivots connecting said rods `and segments near the ends of said segments, spring means associated with said rods for moving the rods and segments outwardly, plates carriedy by the body and having recesses, and rollers carried-bv the segments between their ends and working in said recesses to limit the longitudinal movement of the segments relatively to the body, said recesses having their side walls curved about the corresponding' pivots as centers for the inward swinging movement of the ends of the segments.

In testimony whereof I hereunto affix my signature.
